What horrendous advice. Obviously, there was no attempt to
actually test the advice, or even to read the hook script. And as such,
this advice is wrong. Observe:
,----
| __> dpkg -x /var/cache/apt/archives/initramfs-tools_0.93.2_all.deb root1
| __> cat root1/etc/kernel/postinst.d/initramfs-tools
| #!/bin/sh
|
| # passing the kernel version is required
| [ -z "$1" ] && exit 0
|
| # kernel-package passes an extra arg; hack to not run under kernel-package
| [ -z "$2" ] || exit 0
|
| # we're good - create initramfs. update runs do_bootloader
| update-initramfs -c -t -k "$1"

See where it says that this hook doe snot run under
kernel-package images? maks has not yet had time to upload the patched
hook (he does have other things to do, you know). Now observe the
script below, from kernel-package.
See how it aborts when there is an indication that the
kernel-image does not need an initrd? So that people who are compiling
their own kernels and who do not need an initramfs are not saddled with
one anyway?
See also that it only triggers when the maintainer script is
called with the configure command? See how it supports, like
kernel-package does, having your vmlinuz-* being not in .boot, but
elsewhere?
Weird my foot.
